Questions about this pairing

Which panel is better: Adani Solar ASB-M10-144-525 or Adani Solar AB-G12R-132-620?
According to our database: Adani Solar AB-G12R-132-620 has higher module efficiency (22.97% vs 20.44%); Adani Solar AB-G12R-132-620 tolerates heat better (temp coeff -0.280%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Adani Solar ASB-M10-144-525 and Adani Solar AB-G12R-132-620?
Adani Solar ASB-M10-144-525 has a module efficiency of 20.44%, while Adani Solar AB-G12R-132-620 is 22.97%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Adani Solar ASB-M10-144-525 use vs Adani Solar AB-G12R-132-620?
Adani Solar ASB-M10-144-525 uses PERC cells; Adani Solar AB-G12R-132-620 uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Adani Solar ASB-M10-144-525 and Adani Solar AB-G12R-132-620?
Adani Solar ASB-M10-144-525 has a 30 years power warranty; Adani Solar AB-G12R-132-620 has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Adani Solar ASB-M10-144-525 and Adani Solar AB-G12R-132-620 bifacial panels?
Both Adani Solar ASB-M10-144-525 and Adani Solar AB-G12R-132-620 are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
